Pyramidal anchor stone from Baga waters of Goa, west coast of India
(The Society for Nautical Research, 2002)Underwater exploration in the coastal region off Baga (Goa, India) led to the recovery of an isolated stone artefact, which resembles a pyramidal type of anchor stone. This anchor stone is unlike to other pyramidal anchor ... -
Quaternary phosphorites off the southeast coast of India
(Elsevier, 2002)Detailed petrological, mineralogical, geochemical and radiogenic (U, Sr, Nd) and stable isotope (C, O, S) studies have been carried out on the Quaternary phosphorites of the continental margin off Chennai, southeast coast ... -
Bacterial flora associated with larval rearing of the giant freshwater prawn, Macrobrachium rosenbergii
(Elsevier, 2002)Quantitative and qualitative analyses of bacterial flora associated with larval rearing of the giant freshwater prawn, Macrobrachium rosenbergii, along with important water quality parameters, were carried out over a larval ... -
Diatoms of the microphytobenthic community: Population structure in a tropical intertidal sand flat
(Springer, 2002)Temporal and spatial variations were investigated in the viable diatom population of the microphytobenthic community from an intertidal sand flat of a tropical environment. The presence of diatoms to a sediment depth of ... -
Marine archaeological research in India
(Manohar Publishers and Distributers; New Delhi (India), 2002)Marine archaeology is otherwise known as maritime, nautical or underwater archaeology. These terms include all aspects of marine archaeology in which water plays a dominant role. It deals with the study of past seafaring ... -
Pyloniid stratigraphy - A new tool to date tropical radiolarian ooze from the central tropical Indian Ocean
(Elsevier, 2002)Pyloniid stratigraphy, a faunal abundance-variation stratigraphic tool, similar to Cycladophora davisiana stratigraphy employed at high latitudes, is found to work well for tropical radiolarian ooze. The relationship between ... -
Barium as a productivity proxy in continental margin sediments: A study from the eastern Arabian Sea
(Elsevier, 2002)Barium, aluminium, cadmium and uranium were analyzed in 112 surface sediment samples from the western continental margin, of India. Excess Ba (Ba sub(xs)) concentrations are high at the SW margin of India, an area of high ... -
Over-estimation of sea level measurements arising from water density anomalies within tide-wells - A case study at Zuari Estuary, Goa
(The Coastal Education and Research Foundation, 2002)A 3-year study of water density anomalies within a conventional tide-well indicated that the average water density within the well was consistently lower than that of the external ambient waters. The tide-well at Marmugao, ... -
Antifouling potential of some marine organisms from India against species of Bacillus and Pseudomonas
(Springer, 2002)Crude methanolic extracts of 37 marine organisms (16 species of flora, 21 species of fauna) were screened for antibacterial properties against 5 strains of bacteria isolated from marine environments. Of these, 10 plant and ... -
Seasonal variations in uptake and in situ regeneration of nitrogen in mangrove waters
(American Society of Limnology and Oceanography, 2002)Seasonal changes of uptake of nitrogenous nutrients (NH sub(4) sup(+), NO sub(3) sup(-), NO sub(2) sup(-), and urea) and regeneration (NH sub(4) sup(+) and NO sub(2) sup(-) production) in the plankton fraction of a mangrove ... -
Reconstruction of late Quaternary monsoon oscillations based on clay mineral proxies using sediment cores from the western margin of India
(Elsevier, 2002)In order to reconstruct the variations in the intensity of summer monsoon precipitation during the late Quaternary, two sediment cores from the southwestern continental margin of India were studied for their clay mineral ... -
Mercury and lead tolerance in hypersaline sulfate-reducing bacteria
(Pergamon, 2002)Sulfate-reducing bacteria (SRB) HSR 1, HSR 4, and HSR 14 isolated from the salt pans of Goa, India grew best at 90-100 ppt salinity on substrates like formate, acetate, lactate, butyrate, ethanol and benzoate. They were ... -
Analysis of freshwater flux climatology over the Indian Ocean using the HOAPS data
(Elsevier, 2002)Estimation of freshwater flux over a certain region is very difficult, as it needs both accurate evaporation and precipitation rates over the study area. Over the Indian Ocean (IO), the precipitation estimates are totally ... -

Entry of Vibrio harveyi and Vibrio fischeri into the viable but nonculturable state
(The Society for Applied Microbiology, 2002)Physical responses of marine luminous bacteria, Vibrio harveyi (ATCC 14216) and V. fischeri (UM1373) to nutrient-limited normal strength (35 ppt iso-osmolarity) and low (10 ppt hypo-osmolarity) salinity conditions were ... -
Marine environmental pollution stress detection through direct viable counts of bacteria
(Pergamon, 2002)Direct viable counts (DVC) of bacteria were quantified from polluted and relatively less/non-polluted coastal locations during different seasons to assess whether they can be routinely monitored for an understanding of ... -
Factors regulating the production of different inducers in Pseudomonas aeruginosa with reference to larval metamorphosis in Balanus amphitrite
(Inter-Research, 2002)Gregarious settlement in barnacles has been related to the settlement-inducing compounds from adult conspecifics, bacteria in the biofilms, and their interaction. Elucidation of larval settlement cues from these sources ...
